 * Hirata-san:
  * Did drawings of SR damper.
 * Mark, Fabian, Enzo and Hirata-san (at Kamioka):
  * Took the end plate off the IM to get access to the pitch/roll picos.
  * Found the pitch pico was unreliable and replaced it.
  * Found the springs were not stiff enough, and immobilized 7 turns at the end of each with Cu wire to make them stiffer.
  * Reassembled and rebalanced the IM.
  * Reassembled and adjusted the IRM.
  * Discovered that the transverse offset between IRM and IM could be corrected by adjusting the roll of the BF.
  * Adjusted IM OSEMs to half-way.
  * Made and installed a new pair of wires for the BF yaw pico on the IM pico adapter (Hirata-san).
  * Installed an improved LVDT cable made by Hirata-san.
